How Web Application architecture works? Give Illustration.

Web application architecture refers to the structure and organization of various components that come together to form a functional web application. It involves the arrangement of both front-end (client-side) and back-end (server-side) components, which work together to deliver dynamic content and services over the web. Web applications are typically built using several layers, each of which serves a specific purpose and communicates with other layers to process user requests and present the relevant data.

### Key Components of Web Application Architecture

1. Client-Side (Front-End):
   The client-side is the part of the web application that users interact with directly. It is responsible for the presentation layer and includes everything the user experiences in their browser. The primary technologies used here are HTML, CSS, and JavaScript.

   - HTML (HyperText Markup Language): Defines the structure of web pages.
   - CSS (Cascading Style Sheets): Responsible for the styling and layout of the web pages.
   - JavaScript: Adds interactivity to the web pages by manipulating HTML and CSS dynamically.

   On the client-side, web browsers such as Chrome, Firefox, or Safari render the web pages. The client sends requests to the server, typically through HTTP or HTTPS protocols, and receives responses (usually in HTML, CSS, and JavaScript format).

2. Server-Side (Back-End):
   The server-side is responsible for processing business logic, storing and retrieving data, and handling communication between the client and the server. When a user sends a request, it is routed through the server, which processes the request and sends the necessary data or content back to the client.

   - Web Server: A web server such as Apache, Nginx, or Microsoft IIS listens for HTTP requests from clients and responds by serving files, dynamic content, or processing user requests.
   - Application Server: This is where the main business logic resides. It handles dynamic content generation, authentication, authorization, and interacts with databases to retrieve or store data.
   - Database: Web applications rely on databases (SQL like MySQL, _____ __________ __________ _______ ____ _____ ____ __________ _______ _______ _______ _______.
